Time estimates not working [SOLVED]

bolded textthe remaining time estimates for filament does not work. It shows zero and then N/A about halfway through a print. This is on version 2.02 rc3
The other versions of software did not have this problem. This is also showing up and paneldue except the remaining time is still showing up. the remaining time does not show up on Web interface. It shows N/A

The remaining filament shows N/A however the paneldue shows time remaining
I am wondering if it is because I am using 2 drives for the extruder ( The filament is quite far from the pinter and I had discover that 2 drives prevents any issues ( I had put the drives in series however now I am using 2 separate drives mapped as below
M584 X3:4 Y0 Z2:1 E5:6 ; Apply custom drive mapping

One other note that I forgot to mention. The filament amount is displayed when I initially start the print however it is depleted about halfway through the print and that is when this issues as explained come up

As another note on this issue here are two screen shot of the Paneldue and one of the DWC . These were taken only seconds apart and as you can see the DWC is showing 84% complete while the paneldue is showing more like 25% complete. The panel due is more correct. The filament count on both of these is incorrect.

Here again are the screen shots of Panel Due and DWC but further along in the print
One weird item to look at is that the layer count is screwy on the DWC it states 42 of 33 so perhaps not all layers are being counted. Note also the progress bar shows completed. In the paneldue the progress bar is more or less correct but the filament is n/a

@percar The drive mapping you have in M584 simply assigns drive 3 and 4 to extruders 0 and 1. The important thing is how the tools have been set up to use those drives. How have you set up the tool(s) (M563)? It might be best if you post your config.g file.

@percar, please make available to me (via Dropbox or similar) the GCode file that gives these results. It appears that the firmware is either mis-reading the filament requirement, or mis-calculating the filament consumption.

Yes, that's the reason. You have set the filament mix to 1:1 so it will count filament usage twice as fast as it should. Possible workaround: set the filament mix to 0.5:0.5 and double the extruder steps/mm.
